and'rigidlwhenset up for use. A further object Omy invention is to provide 'a -tailors square havingstraight outer edges and curved inner edges, the( latter conforming to certain curves in the garment and equipped `with certain symbols "alongthe' cur/ed ved es, and ythe straight Cages; ,being provide l*with e `primary fof yon thecurvededges.

Other objects Will a pear hereinafter.

My"`invention `will e more readily understood by reference to the accompanying dravifings forming apart of this specification, and in which, f*

Figure 1 is a plan view of one side of a square embodyingv my invention in its preferred form, Fig. V2is asimilar View of the reverse side, Fig. 3 a planview of one of the joints, the sections being separatedand a portion of the device `beingbroken avvay, Fig. 4 is an edge view of the portion of the device shown in Fig.' 3, Fig. 5 is a section on the line of Fig. 3 upon an enlarged scale, Fig. 6 is a section on the line y-/ of Fig. 5, and Fig. 7 isa view of the corner joint, sections beingseparated."

The square is formed or composed of the long and short arms 1 and 2 respectively, each of which is formed With the straight edges 3 and 4 respectively and the curved inner edges 5 and 6. The edge 5 is convex throughout the greater portion of its length as is also the edge 6, and both merge into a concave curve 7 at the inner corner of the device. The arm 1 is formed of two sections 1 and l connected by a suitable joint l and the arm 2 is composed of a single section connected to the arm 1 by the joint 2 which is diagonally disposed or mitered. Each of the joints is composed of a tongue and a groove formed in the adjacent ends of the sections and extending transversely of the 4several symbols 3 the device wfrom inner to outer edge, and in means for locking 'the parts together". The several sections preferably formed of wood and the members of the joints are formed of metal secured to the abutting edges thereof. Each joint comprises the metal tongue 8, extending from edge to edge of the device and of less thickness 'than its respeotive sectionto'whlch it is secured by the metal strips or plates 9`-9 which overlap i the edge of the section and the nner edge' of the Vtongue, the Wooden section being shouldered' asat 10 to receive them asl shown clearly in Fig. 4. The opposite member of the joint comprises a` pair of parallel plates 11, coextensive in Width `vvith the tongue"8 and secured to 'the shouldered V"edge 12 of its.v 1-espect`ven1ember Ior section o'f the square', Aand forming thegroove'l between them. The bottprn-'ofthegroovel is de'- lined' by "a ba`r`14 againstthe upper""i'ace oi' vvhich the oultergedge 8"'of the tongue rests when `the deviceisset up `for use,"the

outer edges 11" of the plates 11 also abutting tneedgfesv 9 of the plates 9.

The tongue Sis provided with the ins or lugs 15 which enter correspondingsljots' 16 in the plates 1'1. The slots'lA extend 'iii Wardly a"`sut'n`cient distance to permit the edges of the" plates to abut asbeforementioned and are then extended laterally as at 17." VVhen the pins or Alugs 1`5 "are in "the extensions 17 of the slots''it is 'ob'v'i'ou's" that the sections of the device will be held rigidly together.l To lock the Sections this position, the tongue isv provided with "a notch18'and`a spring latch '19 is arranged Within'the oppositemember and projected through the strip "14. When the tongue 8 enters the groove 13 it depresses the latch 19, but as it is moved laterally to bring the lugs into the extensions 17 of the slots, the latch engages the notch 18 locking it in position. The latch comprises a bolt 20 of substantially the thickness of the tongue 8 and groove 13 and extending through an aperture 21 in the member 14 and the shoulders 22 whichv limit its movement. The latch is also provided with the depending ears or flanges 23 in the plane with the plates 11, the corresponding portions of the plates being out away as at 24 to receive them. The ears 23 provide means forfretracting the latch, the plates 11 being grooved or notched as at 25 to receive the finger nail.

26 indicates a spring arranged in a recess 27 formed beneath the member 14C and between the plates ll. The joint 2 is in' every way similar to the joint 1 except that it is angularly disposed at the junction between the arms l and 2.

The curved edges 5, 6 and 7 are shaped to conform to the curved seams such as those occurring at the collar, the baclr andthe arm holes of the garment, and these, especially the curves and 6 are provided with suitable scales 5, 5 and 6. The curve 7, upon both faces of the device is provided with symbols 7', which indicate starting points and at each symbol is a letter which refers the operator to the corresponding scale arranged upon the faces of the device adjacent to the straight edges. To illustrate the mark 7 H refers to scale H indicated at 30 in Fig. 2; or the marlr 7 E of Fig. 2 refers to scale E indicated at 3l in Fig. l. The scales also are arranged to divide the inches into various fractions of an inch. The scales 32 and 33 which are directly at the edges 3 and 4e are inches divided into sixteenths. The scale A indicated at 34 is divided into fourths as is also the scale D, whereas the scales B and E are divided into eighths. The scale C upon the same face (Fig. l) is divided into lifths. Upon the opposite face are arranged the scales F, G, H, I and J which are divided into halves, sixths, ninths, thirds, and two-thirds of an inch respectively.

It is obvious that with the square above described, anyone acquainted with the art may design and cut accurately fitting garments with facility and ease.

Having described my invention what l claim as new and desire to secure by Letters Patent, is:

1. A square of the class described formed of sections and joints detachably connecting the same, each of saidA joints comprising tongue and groove members extending the full width of the blade, a plurality of pins extending laterally from said tongue and the walls of said groove being provided with inwardly extending slots having offset extensions parallel with the joint, substantially as described.

` '2. A square of the class described formed of sections detachably connected the abutting'edges of said sections being provided one with a tongue extending the full width of the blade at that point and the other with a corresponding groove, lugs formed on the sides of said tongue and the walls of said groove being'provided with inwardly extending slots having olfset extensions to receive said lugs, and means for locking said lugs in engagement with said slots, substantially as described.

3. A square formed of sections detachably connected, the abutting edges of said sections being provided one with a tongue and the other with a corresponding groove, lugs formed on the sides of said tongue and the walls of said groove being provided with inwardly extending slots having offset extensions to receive said lugs and a spring latch arranged at the bottom of said groove, the outer edge of said tongue being notched to receive said latch, substantially as described.

l. A tailors square comprising a long and a short arm, said arms having straight outer edges at right angles to each other and curved inneredges, said inner edges being convex throughout the greater portion of their lengths and together merging into a concave curve at the inner angle, the convex curve on the long arm forming a collar curve on one face and a back curve on the other face, and said concave curve forming the armhole curve and having a plurality of symbols upon both faces and said 'square being provided with corresponding scales arranged upon and adjacent to the straight edges, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
